<p>请问在PHS系统中具体是哪个网元最终完成了鉴权？是CSC还是GW？协议中没有写清楚，下面是协议原文</p><p>[9] Authentication (MM)<br/>When the necessary function request declared by the user ends, the network generates an<br/>authentication random pattern, and reports the random pattern by transmitting an authentication request<br/>message (MM) to the user. The user which received the authentication request message (MM) ciphers<br/>the random pattern using the authentication key that he has himself, and it reports the authentication<br/>ciphering pattern to the network using an authentication response message (MM). <strong>The network</strong> that<br/>received the authentication response message (MM) judges whether or not the authentication ciphering<br/>pattern obtained using the authentication random pattern and the authentication key in the home<br/>memory of the user agrees with that reported from the user. If the authentication result is NG, the call<br/>release procedure is initiated according to the regulations of call clearing. If the authentication result is<br/>OK, call connection continues.</p><p></p><p></p>
